Definitions

  • the invention relates to a device for transferring stacks of paper sheets from a first conveyor to a second conveyor with a staging station with several stacking stations arranged next to one another, in which successive rows of stacks are kept ready for the transfer, at least two conveyors, conveying means for loading the staging station with stacks and a transfer means for transporting the stacks from the supply station to the removal device.
  • paper sheets and paper sheet stacks are mentioned in the present context, this does not mean that the invention is limited to sheets and stacks of paper. Rather, it also includes sheets and stacks of other materials such as cardboard, cardboard, plastic and the like.
  • Paper sheet stacks are usually produced in a multi-lane or multi-use manner from a wide paper web.
  • the wide paper web is unrolled from a roll and processed into sheets in successive work processes such as slitting and cross cutting, which are conveyed in several webs one after the other or in a shingled stream to a collecting station, where the sheets of each row are collected into adjacent stacks.
  • the stacks are then removed from the collecting station with a transfer means and transferred to one or more loading conveyors, which convey them to at least one connected packing machine for packaging.
  • DE-OS 27 08 131 is a device of the beginning described type known. There, two packing machines are connected to a production facility, which are connected to the production facility via two loading conveyors. The production facility delivers eight stacks in a row, four of which are transferred to one and four to the other feed conveyor. If a packaging machine fails, the stacks are redirected from the associated feed conveyor to that of the other packaging machine. For this purpose, a rather complicated and complex transverse transport device is provided.
  • the invention has for its object to further improve a device of the type described above.
  • This object is achieved according to the invention in that the transfer means has a number of transfer conveyors and in that the transfer conveyors are driven so as to be controllable individually or in groups. This results in a very flexible transfer device according to the invention, which can remove the stacks in any number ratio from the supply station and distribute them to the discharge conveyors.
  • the claims 2 to 4 relate to a preferred design of the transfer device with a plurality of tong wagons, each having a plurality of tong for gripping the stack in the preparation station. This design is very simple in terms of construction and control technology, yet allows the stacks to be distributed flexibly to the conveyors.
  • Claims 5 to 7 relate to the arrangement of the transfer device in a production device for producing and packaging stacks of paper or stacks of other material.
  • Claim 8 contains features of a currently preferred arrangement of the discharge conveyor relative to the first conveyor.
  • Claims 9 and 10 relate to a further development of the invention, which represents a particularly advantageous embodiment of the discharge conveyor in the area of the transfer device.
  • the division of each discharge conveyor into an intermediate conveyor and a discharge conveyor enables a smooth transition from the discontinuous operation of the transfer device to the continuous operation of the feed conveyor.
  • the invention offers the advantage that the stacks can be divided very flexibly between two or more feed conveyors from a multi-use production facility with a space-saving arrangement. Depending on the needs and requirements, it is possible to distribute the stacks to the feed conveyor in very different numbers. The number ratios can also be changed immediately and quickly. This opens up the very advantageous possibility of reacting flexibly to faults in the connected machines and guiding the stacks in such a way that their reliable further processing and the maintenance of the operation of the production facility are always ensured, even if a packaging machine fails.
  • Figure 1 shows a transfer device according to the invention in a schematic plan view
  • Figure 2 is a sectional view of the same device in the direction of arrows A-B of Figure 1.
  • the transfer device shown in the drawing has a preparation station 1 for stacks 2a and 2b to be transferred, two discharge conveyors 3a and 3b and a transfer means 4 for transferring the stacks 2a and 2b from the preparation station 1 to the discharge conveyors 3a and 3b.
  • the preparation station 1 is designed as a multi-use stacking station, in which the stacks 2a and 2b are formed from sheets 8 fed side by side in shingled streams 6 by means of belt conveyors 7. To form stacks, the sheets 8 run against a stop 9, which can be folded away into the conveying plane 11 to remove the stacks, which is indicated by dashed lines in FIG. 1. This process of stack formation is known per se and therefore requires no further description here.
  • the transfer means 4 has two tong wagons 12a and 12b which are guided in lateral guides and can be moved back and forth between the preparation station 1 and a delivery position in the area of the discharge conveyors 3a and 3b.
  • Guide rods 13 are provided as lateral guides, which are fastened to the machine frame 14 and run in the conveying direction of the belts 7 of the first conveying device.
  • the pliers carriages 12a and 12b can be driven separately from one another by means of motors 16a and b via toothed belt drives 17.
  • each pliers carriage 12a, 12b carries a plurality of pliers 18a and 18b, respectively.
  • the grippers each have an upper jaw 19 and a lower jaw 21 for gripping the paper stack, which are relative to one another
  • Actuating means 22 and 23 are movable.
  • Pneumatic or hydraulic elements can be provided as actuating means 22 and 23, which can be actuated via lines 24 combined in a trailing cable.
  • the discharge conveyors 3a and 3b each have several successive conveyors.
  • intermediate conveyors 26a and 26b are arranged and can be driven separately by means of motors 27a and b.
  • Dispensing conveyors 28a and 28b adjoin these intermediate conveyors 26a and 26b in the conveying direction to the connected further processing machine, which in turn can consist of several successive conveyors.
  • belt conveyors are provided as conveyors, the deflection rollers of which only indicate the axes in dash-dotted lines.
  • the discharge conveyors 28a and 28b can also be arranged aligned on the other side or on both sides.
  • FIGS. 1 to 4 represent different operating phases of the device.
  • the same reference numerals are used in the figures for the same parts. Since the devices are essentially identical, only any existing differences are referred to in connection with FIGS. 3 and 4.
  • the transfer means 4 is controlled so that the two tong wagons 12a and 12b transfer all stacks from the supply station 1 to a single removal conveyor, in the case shown to the intermediate conveyor 26b of the removal conveyor 3b.
  • the intermediate conveyor 26b stands still.
  • the latter is set in motion by means of the motor 27b at a speed which is at least approximately the same as the speed of the continuously rotating delivery conveyor 28b.
  • the stacks are successively transferred to the discharge conveyor 28b without disturbing their configuration.
  • the tong wagons 12a and 12b driven by the belt drives 17 from the motors 16a and 16b, travel to the preparation station 1 in order to take over the next stack.
  • the intermediate conveyor 26b has meanwhile stopped again after the last stack has been delivered to the delivery conveyor 28b.
  • FIG. 3 shows both tong wagons 12a and 12b in their take-over position, in which they take over finished stacks 2a and 2b that are ready in the preparation station 1.
  • the intermediate conveyors 26a and 26b are designed in two parts and each conveyor part 29 and 31 or 32 and 33 is driven separately.
  • the conveyor part 29 is driven by a motor 34 and the conveyor part 31 is driven by a motor 36.
  • the motors of the conveyor parts 32 and 33 are not shown for the sake of clarity.
  • the conveying direction of the intermediate conveyors 26a and 26b and their conveyor parts can be freely selected in accordance with the connected discharge conveyors.
  • both discharge conveyors 3a and 3b convey to the right, for which purpose the discharge conveyors 28a and 28b rotate in the direction of the arrow.
  • the intermediate conveyors 26a and 26b are at a standstill, while the discharge conveyors 28a and 28b are in operation.
  • FIG. 4 shows that each tong carriage 12a and 12b has the same transferred stack 2a or 2b transferred to another discharge conveyor 3a or 3b.
  • the tongs carriage 12a places the stacks 2a it has picked up on the partial conveyor 29 of the intermediate conveyor 26a while the latter is stationary.
  • the partial conveyor 31 of the intermediate conveyor 26a in the meantime rotates at the rotational speed of the discharge conveyor 28a.
  • the tongs carriage 12b transfers the picked stacks 2b in the same way to the partial conveyor 33 of the intermediate conveyor 26b.
  • the partial conveyor 33 stands still during this operation.
  • the partial conveyors 29 and 33 As soon as the stacks from the tongs 12a and 12b have been placed on the partial conveyors 29 and 33, these are set in motion, so that the stacks 2a onto the continuously rotating partial conveyor 31 and further onto the discharge conveyor 28a and the stacks 2b directly onto the discharge conveyor 28b reach.
  • the partial conveyor 32 which is not required for the transfer operation, can stand still in the meantime. While the stacks 2a and 2b are transferred to the conveyors 3a and 3b, new stacks are formed in the preparation station 1, as shown in FIG.
  • This means that the stacks 2a in this configuration of the intermediate conveyor 26a are subjected to an additional stopping and accelerating operation which entails the risk of disturbing the stack configuration.
  • the stacks 2b become the intermediate conveyor in this one-piece design passed directly to the discharge conveyor 28b in the next work step and are not subject to this additional stress.
  • the division of at least the intermediate conveyor 26a into two partial conveyors 29 and 31 has the advantage that the stacks 2a discharged from the partial conveyor 29 from the transfer position of the transfer means can be passed on to the discharge conveyor 28a without an additional stop if the adjacent partial conveyor 31 and the discharge conveyor 28a is continuously driven and thereby practically represents an extension of the discharge conveyor 28a to the partial conveyor 29.
  • the division of the intermediate conveyors into partial conveyors thus avoids an additional load on the stack and is particularly advantageous when working at high speeds to achieve a high conveying capacity.
  • FIG. 5 shows an embodiment of the invention in which all pliers 38 are individually guided on guides 37 and driven by motors 39.
  • rodless band cylinders can be used, which are commercially available.
  • This embodiment of the invention allows a very individual adjustment of the loading rates of the two discharge conveyors 28a and 28b. This also enables the stacks to be divided between the two discharge conveyors, which deviates from the ratios 0: 1 and 1: 1. This device can be controlled so that the stack transfer to the discharge conveyor can be set very flexibly to the most varied of operating conditions.
  • FIG. 1 separate motors 27a and b are provided for the intermediate conveyors 26a and b, so that they can be driven independently of one another. It is also possible that Drive intermediate conveyors together with a single motor. For better clarity, the drives for the partial conveyors 32 and 33 are not shown in FIGS. 3 and 4. The drive design shown contributes significantly to the great flexibility of the device and ensures gentle removal of the accumulated stacks.
